Problems solved by technology

[0004] First, the cost requirement is too high, the purity of copper will affect the antibacterial performance of the fiber, and the cost of metal powder preparation and processing is relatively high, so the cost of purely using copper powder to achieve antibacterial effect is unacceptable for traditional textiles;
[0005] Second, the mechanical properties of fibers are poor. Copper-based powders are an active metal material, especially small particles, which will have certain catalytic performance in the future, making the mechanical properties of fibers worse;
Although this method is cheap and effective, it also has inevitable defects:
[0009] (1) Additional pollution. At present, antibacterial agents are generally used for finishing, which increases the degree of pollution of wastewater and increases the difficulty of wastewater treatment;
[0010] (2) The durability is not enough. The antibacterial finishing method currently used has poor washability, and generally has little washability that can meet the standard requirements, which is not conducive to the export of textiles, reduces the competitive advantage of textiles, and increases trade. dispute

Abstract

The invention provides a preparation method of compound antibacterial deodorizing functional masterbatch and fibers. The preparation method of compound antibacterial deodorizing functional masterbatch comprises surface modification of copper serial powder, configuration of functional compound resin powder and preparation of the compound antibacterial deodorizing functional masterbatch. The novel antibacterial deodorizing functional masterbatch and fibers prepared by a brand new antibacterial compound mechanism have a permanent antibacterial function, the mechanical property can reach the standard of common fibers, various weaving demands can be fully met, the cost is equivalent to that of antibacterial post-treatment, and the pollution is reduced. According to the preparation method provided by the invention, export of textiles can be expanded, and the additional value of the textiles is increased.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and in particular relates to a method for preparing composite antibacterial and deodorizing functional masterbatches and fibers. Background technique [0002] With the improvement of living standards, the demand for fabric antibacterial function is gradually increasing. At present, there are some solutions, such as solving the problem from the source of the fiber, which can prepare antibacterial fibers. For example, silver antibacterial system was used in the past, which can achieve good antibacterial effect. However, the migration of silver ions is also a potential threat, which will affect normal cells. Therefore, the copper ion antibacterial system is currently advocated, and it is currently widely used in some fields of medical hygiene and household textiles. [0003] But such fibers also have irreparable defects: [0004] First, the cost requirement is too high, the pur...
